A pawl 20 is pivotally mounted on a and since the scale mechanism per se is of a transverse rod 21 which is secured to the bracket 1b 15 and to a rear plate 22 which is connected to the bracket 15. fhe pawl 20 is pivoted to move freely upon this rod 21 and a spring 23 is connected to hold the pawl in engagement with the ratchet wheel 18. To the outer end of the tubular member 17 is fixedly connected an operating dial 24, said dial bearing indicia on the periphery thereof to correspond with the type on the periphery of the printing wheel 14. A second tubular member 25 is mounted interior of the tube 1'7 to rotate freely therein, the inner end of said tubular member having the type wheel 13 and ratchet 26 secured thereto in a similar manner to the type wheel 14 and ratchet wheel 18 and having an operating dial 27 secured to the outer end thereof in the same manner as the operating dial 2%. Within the inner tubular member 25 a shaft 28 is mounted to be freely rotatable therein, said shaft having-the type wheel 12 and ratchet wheel 29 secured to the inner end thereof similarly to the type wheels 13 and 14 and ratchet wheels 18 and 26, said shaft extending through the type wheel 12 and having free pivotal bearing in an opening in the plate 22. An operating dial 30 is fixedly secured to the outer end of the shaft 28. These type wheels may be individually set in any desired position so as to bring the desired type into alinement and opposite the ticket upon w ic it is to be printed.

An inking ribbon 31 passes over rollers 32, 33, 34, 35, and 36. A weighted roller 37 being supported on links 38 places a tension upon the ribbon and prevents sagging thereof. A roll 39 of ticket material is mounted upon a spindle 40 and the strip of tickets is fed upwardly over a roller 41, a second roller 42, and is threaded down between metal guides 43 and 44 and through a guide member 45. This guide member is fiat on its lower surface and forms a slidable support for a ticket severing knife 46. The forward edge of the opening in the guide through which the ticket is fed forms a stop against which the ticket is held, while being severed with the knife. The severing knife is mounted upon a block 47, as indicated in Figure 5, the knife being held in position by pins 48 and 49 fixed in the supporting block a7 and being freely insertible in apertures in the severing knife. Four coil springs 50, 51, 52, and 53 are positioned in recesses in the severing block and exert an upward pressure on the knife to resiliently hold it in engagement with the lower surface of the ticket guide member 45. A recess 55 in the forward edge of the supporting member 47 has a rubber striking hammer 56 set therein to force the ticket into engagement with the type on the type wheels to cause an impression to be printed on the ticket. A spring ticket-supporting member 57 is provided above the hammer to hold the ticket in position after severing until the printing operation is completed. This entire structure is supported on a ticket slide member 47a which in turn supports a bracket 58 and the ticket guide member 43 and plate 59. The plate 59 has an elongated slot 60 therein, best shown in Figure 9, with narrowed central portion and enlarged end portions 61 and 62. A pin 63 is positioned to ride in the slot 60, being supported in a cam block 64, the pin being normally held in a central position in said block by means of coil springs 65 and 66 mounted to rest on the inner and outer stufaces of said block, respectively, and to engage the enlarged outer end of a head 6'7 of said pin and a washer 68 secured near the inner end of said pin, respectively. This cam block is provided with angularly disposed recesses 69 in each side thereof, said recesses being adapted to have a free sliding fit over angularly disposed track members '70 mounted one on each side of said block and held by arms '71 and '72 which are fixedly secured to the housing 13 of the mechanism. A link '73 has pivotal connection with the block 64 and has a slot '74 therein which rides over a pin '75 positioned transversely of the support member 47, as best shown in Figures 3 and 3. The lower end of the link '73 is connected eccentrically to a rotatable member '76 which is arranged (by means of mechanism shown generally in Figure 2, but which is not pertinent to the present invention and, therefore, is not described in detail in the present application), to make one complete revolution upon each actuation of the mechanism.

A laterally extending link 77 is constructed with a slot '78 which rides a pin 7 9 mounted on the vertical link '73. A pawl 80 is provided on the link 77 which pawl engages a ratchet 81 connected to the roller 36 around which the inking ribbon 31 is passed. Upon each actuation of the mechanism the link is advanced and retracted so as to advance the ratchet 81 by means of the pawl 80 and to thereby advance the inking ribbon.

The operation of the mechanism is as follows:

Upon being released and actuated by the suitable associated mechanism not herein described in detail, the rotatable member '76 is rotated one complete revolution counter-clockwise. The link 73 starts from its lowermost position and is moved first to the right and upward during the first quarter of the cycle of the rotatable member, and then to the left and up during the second half of said cycle, then to the left and downward during the third quarter and to the right and downward to the starting point during the fourth quarter.

During the upward travel of the link 73 the block 64 is slidably moved upward along the track members 70. At the upper end of its travel this block is positioned forwardly on the members 79 and the inner coil spring 66 is compressed to force the pin 63 forwardly through the plate 59, the pin being at this point opposite the enlarged upper portion 61 of the slot 60. The inner washer 83 will pass through this enlarged portion of the slot so as to bring the washer 83 on the inner or ticket side of the plate 59, forcing the pin into engagement with the ticket.

During its downward travel the block 64 will be moved away from the plate 59 by the increased distance of the track members '70 from the plate 59 at their lower ends. this downward travel Will be retained inside the plate 59, riding on the sides of the narrow portion of the slot 60, holding the inner end of the pin 63 into engagement with the ticket. The coil spring 65 will be compressed during this movement, tending to force the pin outwardly as e the block reaches the lower end of its travel. As the washer 83 comes into registry with the enlarged lower portion 62 of the slot 60, the outer coil spring 65 will force the pin outwardly out of engagement with the ticket strip 39. The normal position for the operating mechanism is with the block 63 at its lowermost position.

The parts are shown after completing onehalf cycle in Figure 3, and after the completion of one quarter cycle in Figure 2.

During the first half of the cycle the support member 47 will be moved forward, severing the ticket by means of the severing knife 46. The spring ticket holding member 57 at the same time The washer 83 during forces the ticket into engagement with the type wheels to prevent it from prematurely dropping down into the discharge chute. Further forward movement of the support block 47 brings the rubber striking hammer 56 into engagement with the ticket to force it against the type, on the type wheels, causing an impression of said type to be printed on the ticket. As the rotatable member 76 continues its cycle of operation the block 64 and associated parts will be withdrawn, releasing the spring 57 from engagement with the ticket and permitting the severed, printed ticket to drop into the discharge chute. During the second half of the cycle the pin 63 will engage the ticket strip and feed downwardly a suflicient amount of ticket material for the next ticket as hereinbefore described.

The manually rotatable type wheels may contain designations of the months, days of the month, and years, and these may be manually adjusted by means of the actuating members 24, 27, and each morning, so that the proper date will be imprinted upon the tickets for that day.

While primarily designed for use in a scale, it is not desired to limit the ticket printing mechanism to use with a scale, but it may be used with any desired mechanism which requires a ticket printing mechanism of this general character.
